PSP Memory Stick Pro Duo Suggestions?

Recently my 4 GB Pro Duo memory card broke and I'm on the market for another 4 GB (or higher) card. It seems like there are a lot of offerings just from scanning Amazon and Newegg, so I want to know if you guys and gals have any suggestions? A couple I've been looking at are:

Oh, and I'd like to spend under $30 if possible. Thanks...

 

I'm not sure if High Speed cards make a difference, so just go for the 8GB on Amazon if you need the space. If not, just stick with a 4GB one. Cheaper is better though.

 

Sandisk Ultra II sticks. A lot faster than the regular sticks, don't buy Sony.

And stay away from DealExtreme, eBay, and third-party sellers from Amazon, Newegg you don't have to worry about.

 

Thanks you two. I ended up going with this one:

I think it should be enough storage (same amt. as it's replacing) with a little added speed at a nice price.

 

Congrats on the purchase

I say from experience that when running apps or games from the memory card, a card with a higher speed helps loading and reduces lag.

Problem was that the faster one was 1Gb and the other 4 (same as your BTW)
